  • Abstract:
    This study investigated the feasibility of using fiber optic sensors to capture traffic data. Funding from the ; study was used to develop a prototype sensor using fiber Bragg gratings (FBG) technology. The sensor was ; tested on a high volume portland cement concrete highway and found to be feasible for use in monitoring ; light and heavy traffic. Signals from the senor were processed with a demodulator system, and captured on a ; computer. For testing purposes, the signal was converted to a scaled analog voltage signal and successfully ; output to a conventional traffic classifier recorder. ; The sensors have the potential for long-lasting, cost-effective solutions in vehicle classification applications. ; With modification, the FBG strain sensor shows potential for use in weigh-in-motion applications. ; The system is sensitive enough to detect adjacent lane traffic, opening possibilities of shoulder area ; monitoring for less traffic disruption and increased safety. With two sensors, the system can capture speeds ; as well as weights of both sides of a vehicle. ; Future development of dedicated demodulator/interfacing electronic hardware and auto-tuning grating system ; could eventually lead to cost effective solutions for traffic classification and weigh-in-motion applications.
